BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to status reporting devices for container handlers and methods of making these devices. A container handler will refer herein to a device, usually operated by a human operator, which moves a container of at least twenty feet in length.

2. Background Information

Container terminals are transfer points between marine and land-based shipping. These container terminals must maintain inventory control for an ever-increasing number of containers. The basic unit of transfer is a container, which comes in five sizes, a ten foot, a twenty foot, a thirty foot, a forty foot and a forty five foot size. These containers, when filled, may weigh up to 110,000 pounds, or 50,000 kilograms, making them impossible to move, except by machinery.

The last few years have seen increased demand for real-time reporting of container activity throughout the container terminals.

The point of transfer between marine transport and land-based transport is the quay side crane, or quay cranes, as they will be known hereafter. Berthing operations involve transferring containers between a container ship and a land transport by one of these quay cranes. There is often a need for mechanisms to inspect the containers and/or create long lasting records of the visual condition of the containers at the time of transfer. The clerks involved may intentionally or unintentionally mislead the container inventory management system and the terminal management. The container's contents may be damaged when it reaches its destination, leading to the possibility of lawsuits and insurance claims being brought against terminal management. Berthing operations may be seen as loading and unloading containers onto container ships.

The quay cranes deliver the containers onto UTR trucks, which sometimes carry the containers on specialized chassis known as bomb carts. The UTR trucks move containers around a terminal, transferring the containers between one or more stacking yards and the Quay cranes. In the stacking yards, a number of different cranes may be used to place the container in stacks, or possibly load them onto or unload them from trucks used for container movement outside the terminal.

There is an ever growing need to continuously monitor the status of the container handlers around a terminal. Overall terminal efficiency tends to be improved if the terminal management knows the status and/or location of each container handler and each container in the terminal. Illicit use of container handlers may be minimized by use of operator identification devices. The container codes may be observed and recorded at various points in the terminal transfer operations. Photographs may be taken of the container conditions as it is leaving a ship, or being put on a ship.

There is however a problem of scale. While there are millions of containers entering and leaving a country such as the United States annually, there are nowhere near that many container handlers. Even worse, there are many different kinds of container handlers. Some, such as UTR trucks, Front End Loaders (FEL), and bomb carts handle containers differently from the cranes. As used herein, Front End Loaders will refer to Top Handlers (also known as Top Loaders) and Side Handlers (also known as Side Pickers). The crane based container handlers vary in structure greatly. Some have centralized controls, known as Programmable Logic Controllers (PLC), and some do not. As a consequence, these reporting devices, which enable container tracking, represent small production runs. These small production runs involve many variations in circuitry and couplings for these different types of container handlers, with the attendant high setup and manufacturing costs. A modular manufacturing method is needed for these reporting devices, which can readily account for the container handler variations, while minimizing cost and maximizing reliability.

In the last few years, a variety of radio frequency tagging devices have entered the marketplace. These devices can often provide a mechanism for identifying themselves, as well as reporting their location via a wireless communication protocol, often one or more variants IEEE 802.11. Some of these devices rely on a local wireless network to aid them in location determination. While these devices have uses, they do not satisfy all the needs that container handlers have for status reporting. What is needed are mechanisms and methods for using the capabilities of radio frequency tagging devices to provide an integrated solution to the needs of the various container handlers, to report on the container handler status, and/or provide observations of the container being handled.

BRIEF SUMMARY OF THE INVENTION

The invention includes a mechanism and a method for making status reporting devices for container handlers. The devices are manufactured in a modular, highly efficient manner, which is able to use a relatively small number of different parts to serve the needs of a wide variety of container handlers.

A container handler will refer herein to a device, usually operated by a human operator, which can move a container of at least twenty feet in length. International commerce primarily uses containers of approximately ten feet, twenty feet, thirty feet, forty feet or forty-five feet in length.

The method making the status reporting devices includes the following steps. A micro-controller module is provided. A program system is installed into a memory, which a computer can access to direct the micro-controller module.

The micro-controller module is communicatively coupled with a means for wirelessly communicating and a means for sensing a state of the container handler.

The program system includes program steps residing in the memory. These program steps include the following. Using the means for sensing the state of the container handler to create a sensed state. And using the wirelessly communicating means to communicate the sensed state of the container handler.

In many preferred applications of the status reporting device, the means for wirelessly communicating is linked to a container inventory management system, sometimes also known as a terminal operating system. The sensed state may be preferably communicated to another computer, preferably associated with the terminal operating system.

The means for sensing may include, but is not limited to, means for any combination of the following.

-   -   Sensing an operator identity.     -   Sensing a container presence on, or coupled to, the container         handler.     -   Optically sensing a container code on a container.     -   Radio frequency sensing a radio frequency tag on the container.     -   Sensing a stack height for the container.     -   Sensing at least one member of a machine state list of the         container handler. The machine state list may include reverse         motion, frequent stops count, collisions, fuel level, and         compass readings. The machine state list may further include a         wind speed and an equipment up-time.     -   Sensing at least one member of a crane state list. The crane         state list may include a twistlock sensed state, a spreader         sensed state, a sensed landing state, a trolley position, and a         hoist height.     -   Sensing the container size.     -   Sensing the container weight.     -   Sensing container damage.

The means for wirelessly communicating may include a means for wirelessly determining the location of the container handler. Alternatively, the micro-controller module may be communicatively coupled to an at least partially separate means for locating the container handler. The means for locating may include an interface to a Global Positioning System (GPS). The means for wirelessly communicating may include a radio location-tag unit.

The container handler is at least one member of a container handler list comprising an UTR truck, a bomb cart, a rubber tire gantry crane, a quay crane, a side picker, a top loader, a top handler, a reach-stacker, a straddle carrier, and a chassis rotator.

The memory may include a non-volatile memory, which may further contain at least part of at least one of the program steps of the invention. Installing the program system may include altering at least part of the non-volatile memory, or installing a memory module containing at least part of at least one of the program steps in the non-volatile memory, creating at least part of the memory, which can be accessed by the computer. As used herein, the computer may be part of a micro-controller.

The invention includes apparatus for making the status reporting devices. The apparatus may include a second program system directing the implementation of the invention's method residing in memory accessibly coupled to a second computer. The second computer may control an assembly device receiving the micro-controller module, the means for wirelessly communicating, and the means for sensing the state of the container handler to create the reporting device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The invention includes an apparatus and a method of making at least one, preferably many status reporting device 800 for at least one, preferably many container handler 78. The manufacturing proceeds in a modular, highly efficient manner, which is able to use a relatively small number of different parts to serve the needs of a wide variety of container handlers.

A container handler 78 will refer herein to a device, usually operated by a human operator, which moves a container 2 of at least twenty feet in length. International commerce primarily uses containers of approximately twenty feet to forty five feet in length. Containers when filled with cargo may weigh up to 110,000 pounds, or up to 50,000 kilograms. The width of the container 2 may be at least eight feet wide. The height of the container may be at least eight feet six inches.

As used herein, a container handler 78 will refer to at least one of the members of the container handler list 80 shown in FIG. 4B. The container handler list 80 includes, but is not limited to, the following.

-   -   The UTR truck 10, the bomb cart 14, and the Rubber Tire Gantry         crane 20, often abbreviated RTG crane are shown in FIG. 1. Note         that the bomb cart 14 is also known as a container chassis, when         the container 2 is tied down. Within container terminals,         containers are not typically tied down to bomb carts.     -   The quay crane 30 is shown in FIG. 2.     -   The side picker 40 is shown in FIG. 3A.     -   The reach stacker 46 is shown in FIG. 4A.     -   The top handler 50 is shown in FIG. 4C.     -   The straddle carrier 54 is shown in FIG. 4D.     -   The chassis rotator 58. The chassis rotator is used to rotate         the chassis used to haul one or more containers. It operations         and requirements are similar to other contain handlers, except         that its rectilinear position is fixed. More relevant for these         container handlers is the use of its location 1900 as an angular         measure of its orientation of the container 2. The means for         determining 1500 the location 1900 consequently may use a shaft         encoding, possibly an optical shaft encoder.

The rubber tire gantry crane 20 of FIG. 1 may be called a transfer crane and/or a TRANSTAINER™. The quay crane 30 of FIG. 2 is sometimes referred to as a PORTAINER™. The side picker 40 of FIG. 3A is also referred to as a side handler or a side hauler. The top loader 50 of FIG. 4C is also referred to as a top picker or top handler.

Some of these container handlers have the ability to lift and/or place a container 2. A container handler 78 able to lift and/or place the container is a member of the stacking handler list of FIG. 4B, which includes, but is not limited to, the following.

-   -   The rubber tire gantry 20 of FIG. 1 includes a rubber tire         gantry spreader 22.     -   The quay crane 30 of FIG. 2 includes a quay crane spreader,         which is outside the picture.     -   The side picker 40 of FIG. 3A includes a side picker spreader         42.     -   The reach stacker 46 of FIG. 4A includes a reach stacker         spreader 48.     -   The top handler 50 of FIG. 4C includes a top handler spreader         52.     -   The straddle carrier 54 of FIG. 4D includes a straddle carrier         spreader 56.

FIG. 3B shows a stack of containers including first container 60 to fourth container 66 defining what is referred to herein as a stacking height.

-   -   The stacking height of the first container 60 is usually denoted         as one.     -   The stacking height of the second container 62 is two.     -   The stacking height of the third container 64 is three.     -   And the stacking height of the fourth container 66 is four.     -   While this is a standard designation, any other designation may         be used within a computer, such as numbering as follows, first         container 60 as zero, second container 62 as one, third         container 64 as two, and fourth container 66 as three.     -   In some situations, container stacks may preferably include more         than four container stacked on top of each other, for example,         up to seven containers high.

FIGS. 5A and 5B show two examples of a housing 3000 of the status reporting device 800 for use on various members of the container handler list 80.

-   -   The housing 3000 of FIG. 5A includes a housing mount 3002, by         which it may be preferably attached to a rubber tire gantry         crane 20 of FIG. 1 and/or quay crane 30 of FIG. 2. The housing         3000 may preferably contain at least part of the means for         optical container code sensing 1230.     -   The housing 3000 of FIG. 5B preferably includes a display 3010.         The housing 3000 may preferably be attached to any member of the         container handler list 80.

FIG. 6A shows a system for making 100 a status reporting device 800 for a container handler 78 of FIGS. 13A and 13B. The container handler 78 is a member of the container handler list 80. Some preferred embodiments of the status reporting device 800 for specific members of the container handler list 80 are shown in FIGS. 17 to 25.

In FIG. 6A, the system for making 100 includes a means for providing 200 a micro-controller module 1000.

-   -   The status reporting device 800 includes a first communicative         coupling 1102 of the micro-controller module 1000 with a means         for wirelessly communicating 1100. and     -   The status reporting device 800 includes a second communicative         coupling 1202 of the micro-controller module 1000 with a means         for sensing state 1200 of at least one member of the container         handler list 80 of FIG. 4B.

In FIG. 6A, the system for making 100 also includes means for installing 300 a program system 2000. The program system 2000 is installed into 302 a memory 1020.

-   -   The micro-controller module 1000 includes an accessible coupling         1022 of a computer 1010 with the memory 1020.     -   The computer 1010 directs the activities of the micro-controller         module 1000 through a program system 2000. The program system         2000 includes program steps residing in the memory 1020 as shown         in FIGS. 6A and 16A.

The method of operating the status reporting device 800 will be discussed as implemented by the program system 2000. One skilled in the art will recognize that alternative implementations, which may include, but are not limited to, finite state machines, neural networks, and/or inferential engines are possible, feasible, and in certain circumstances, potentially preferable.

A computer as used herein may include, but is not limited to, an instruction processor and/or a finite state machine, and/or an inferential engine, and/or a neural network. The instruction processor includes at least one instruction processing element and at least one data processing element, each data processing element controlled by at least one instruction processing element.

An embodiment of the computer, as used herein, may include not only what some would consider peripheral circuitry, which may include, but is not limited to, communications circuitry, memory, memory interface circuitry, clocking and timing circuitry, as well as signal protocol interface circuitry.

-   -   These circuits may be fabricated in the same package as the         computer, sometimes on the same semiconductor substrate as the         computer.     -   While some of these circuits may be discussed separately from         the computer, this is done to clarify the operation of the         invention and is not meant to limit the scope of the claims to         mechanically distinct circuit components.

Embodiments of the status reporting device 800 may include determining the location 1900 of a container handler as shown in FIG. 6A.

-   -   These aspects will be discussed later regarding the means for         determining 1500 the location 1900 of the container handler as         in FIGS. 14A to 14C, 15B, 17, 18, 21, 22, and 24.     -   Other alternatives may include, but are not limited to, using a         means for wirelessly communicating 1100 which includes a means         for wirelessly determining 1510 for locating the container         handler, as discussed in FIGS. 15A, 19, 20, 23, and 25. These         aspects of the invention may not require the storage of the         location 1900 in the computer 1010 of FIG. 6A.

Some of the following figures show flowcharts of at least one method of the invention, possessing arrows with reference numbers. These arrows will signify of flow of control and sometimes data supporting implementations including

The operation of termination in a flowchart is designated by an oval with the text “Exit” in it, and refers to the completion of those operations, which may result in at least one of the following:

-   -   return from a subroutine return,     -   traversal of a higher node in an inferential graph,     -   popping of a previously stored state in a finite state machine,         and/or     -   return to dormancy of the firing neurons of the neural network.

FIG. 6B shows the program system 2000 of FIG. 6A, which the means for installing 300 installed into 302 the memory 1020.

-   -   Operation 2012 supports using the means for sensing state 1200         of FIG. 6A for sensing the state of the container handler 78 of         FIGS. 13A and/or 13B, to create a sensed state 1800.     -   Operation 2022 supports using the means for wirelessly         communicating 1100 to communicate the sensed state 1800 of the         container handler 78.

One skilled in the art will recognize that the means for sensing state 1200 may further preferably include specific sensors and interfaces beyond those related with FIGS. 13A and/or 13B.

This mechanism and process is similar to the various         embodiments of the means for coupling 210 which creates the         coupling 212, which will be described in greater detail.

FIG. 7B shows a detail flowchart of operation 2022 of FIG. 6B further using the means for wirelessly communicating 1100.
